[0001] This invention relates to the field of door manufacturing technology, and in particular to a door panel and a sliding door. Background Technology

[0002] Sliding doors are ubiquitous in daily life, for example, in the entrances and exits of residential communities. However, in related technologies, the door panels of sliding doors are not adjustable, making them unsuitable for entrances and exits of different sizes. Utility Model Content

[0003] This application provides a door panel and a sliding door, wherein the door panel is adjustable in size to accommodate different sized access passages.

[0004] In a first aspect, this application provides a gate, the gate comprising:

[0005] The main door assembly includes two first crossbeams spaced apart vertically, each first crossbeam having a receiving space.

[0006] A secondary door assembly, comprising two second crossbeams spaced vertically apart, the second crossbeams being retractably inserted into the receiving space of the first crossbeams along a predetermined direction; and

[0007] A locking assembly is provided between the two first crossbeams and the two second crossbeams. The locking assembly presses against the first crossbeams and the second crossbeams to prevent the second crossbeams from moving relative to the first crossbeams along the preset direction.

[0008] In some embodiments, the locking assembly includes a diagonal brace disposed within the receiving space and located between the inner wall surface of the first crossbeam and the outer wall surface of the second crossbeam; the diagonal brace presses against the inner wall surface of the first crossbeam and the outer wall surface of the second crossbeam to fix the first crossbeam and the second crossbeam together.

[0009] In some embodiments, the locking assembly further includes an outer bushing and a first fastener. The outer bushing is fixed to the end of the first crossbeam and has a first mounting hole. The first fastener passes through the first mounting hole and is connected to the diagonal brace. The diagonal brace and the outer bushing work together to press the first crossbeam and the second crossbeam so that the first crossbeam and the second crossbeam are fixedly connected.

[0010] In some embodiments, the outer bushing is provided with a groove that mates with the diagonal brace, and the diagonal brace is disposed within the groove.

[0011] In some embodiments, the outer bushing is annular, and the outer bushing is fitted onto the second crossbeam and fixed to the end of the first crossbeam.

[0012] In some embodiments, the diagonal brace is provided with a second mounting hole, and the first fastener is inserted into the second mounting hole and threadedly engaged with the second mounting hole.

[0013] In some embodiments, the diagonal brace is a rubber or plastic component.

[0014] In some embodiments, the locking assembly includes a locking member, a portion of which is fitted around the outer periphery of the first crossbeam to compress the first crossbeam, and another portion of which is fitted around the outer periphery of the second crossbeam to compress the second crossbeam, thereby preventing the second crossbeam from moving relative to the first crossbeam along the predetermined direction.

[0015] In some embodiments, the locking member includes a first sleeve and a second sleeve, the first sleeve having a communicating first receiving cavity and a first opening, the first receiving cavity being used to receive the first crossbeam; the locking assembly further includes a second fastener connected to the first sleeve and used to adjust the size of the first opening to change the size of the first receiving cavity.

[0016] The second sleeve has a communicating second receiving cavity and a second opening, the second receiving cavity being used to receive the second crossbeam; the locking assembly further includes a third fastener connected to the second sleeve and used to adjust the size of the second opening to change the size of the second receiving cavity.

[0017] In some embodiments, the first sleeve includes a first pressing part, a first connecting part, a second pressing part, a first adjusting part, and a second adjusting part; the first adjusting part, the first pressing part, the first connecting part, the second pressing part, and the second adjusting part are sequentially bent and connected and together form the first receiving cavity; the first adjusting part and the second adjusting part are opposite to each other and spaced apart to form the first opening, and the first adjusting part and the second adjusting part are connected to the second fastener;

[0018] The second set includes a third extrusion part, a second connecting part, a fourth extrusion part, a third adjusting part, and a fourth adjusting part; the third adjusting part, the third extrusion part, the second connecting part, the fourth extrusion part, and the fourth adjusting part are sequentially bent and connected and together form the second receiving cavity; the third adjusting part and the fourth adjusting part are opposite to each other and spaced apart to form the second opening, and the third adjusting part and the fourth adjusting part are connected to the third fastener.

[0019] In some embodiments, the locking element is a rubber or plastic component.

[0020] Secondly, this application provides a sliding door, which includes a front main frame assembly, a rear main frame assembly, and a door panel. The main door panel assembly of the door panel is rotatably connected to the front main frame assembly, and the secondary door panel assembly of the door panel can be detached from or connected to the rear main frame assembly.

[0021] In the door panel provided in this application, since the second crossbeam is retractably inserted into the first crossbeam, the overall width of the door panel composed of the main door panel assembly and the secondary door panel assembly can be adjusted, thereby adapting to access passages of different sizes. Furthermore, because the locking assembly exerts a compressive effect on the first and second crossbeams, when the first or second crossbeam is subjected to an external force from a preset direction, the locking assembly creates a frictional action along the preset direction on the compressed first and second crossbeams. This frictional action prevents the first and second crossbeams from moving relative to each other in the preset direction. Therefore, the locking assembly can lock and fix the main door panel assembly and the secondary door panel assembly together. Attached Figure Description

Detailed Implementation

[0042] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0044] Please refer to Figure 1 and Figure 2 In related technologies, the door panel of the sliding door 100' is not adjustable, making it unsuitable for different sized access passages. The door panel of the sliding door 100' consists of two parts: a main door panel assembly 110' and a secondary door panel assembly 120', which are locked together by self-tapping screws 190'. However, the above-mentioned solution of directly using self-tapping screws 190' for locking is prone to the following problems:

[0045] (1) If the second crossbeam 121' of the auxiliary door assembly 120' is made of metal, since the self-tapping screw 190' is drilled directly in the screw hole of the second crossbeam 121', the screw hole is prone to water seepage. Therefore, in outdoor or humid environments, the screw hole on the second crossbeam 121' is very prone to oxidation and rust.

[0046] (2) Vibration will occur when the door is opened and closed. Over time, the self-tapping screws 190' will loosen, making the connection between the first crossbeam 111' and the second crossbeam 121' unstable.

[0047] Based on this, this application aims to provide a solution that can solve, but is not limited to, the above-mentioned technical problems, the details of which will be described in subsequent embodiments.

[0048] Please refer to Figure 3 This application provides a sliding door 100, which can also be called a swing door, a swing gate, etc., and can be used, but is not limited to, in the access passages of residential areas, schools, warehouses, and factories.

[0049] The sliding door 100 includes a first main frame assembly 20, a last main frame assembly 30, and a door panel 10 as described in any of the following embodiments. The first main frame assembly 20 and the last main frame assembly 30 are spaced apart and opposite to each other. The main door panel assembly of the door panel 10 is rotatably connected to the first main frame assembly 20, meaning the door panel 10 can rotate around the first main frame assembly 20. The secondary door panel assembly of the door panel 10 can be detached from or connected to the last main frame assembly 30; that is, there are two possible relationships between the door panel 10 and the last main frame assembly 30: either the door panel 10 and the last main frame assembly 30 are separate, or the door panel 10 and the last main frame assembly 30 are fixed together.

[0050] From another perspective, the sliding door 100 has two states: an open state and a closed state. When the sliding door 100 is in the open state, the door panel 10 is disengaged from the rear main frame assembly 30; when the sliding door 100 is in the closed state, the door panel 10 is connected to the rear main frame assembly 30. During the switching between the open and closed states, the door panel 10 rotates around the front main frame assembly 20.

[0051] The gate panel 10 and the first main frame assembly 20 can be rotatably connected via, but are not limited to, a top and bottom pivot. The gate panel 10 and the rear main frame assembly 30 can be controllably disconnected or connected via, but are not limited to, an electromagnetic lock.

[0052] The following section, with reference to the attached diagram, provides a detailed description of the door panel 10 in the sliding door 100.

[0053] Please refer to Figure 3 and Figure 4This application provides a door panel 10, which includes: a main door panel assembly 110, a secondary door panel assembly 120, and a locking assembly 130.

[0054] The main door assembly 110 is used to rotatably connect to the first main frame assembly 20. The main door assembly 110 includes two first crossbeams 111 spaced vertically apart and multiple first vertical rods 112. The multiple first vertical rods 112 are spaced apart along the extension direction of the first crossbeams 111 and connected to them. The spacing between the multiple first vertical rods 112 can be the same or different. The first crossbeams 111 have a receiving space Q (e.g., ...). Figure 4 As shown in the diagram, the first horizontal beam 111 is a hollow structure. Of course, the vertical rods can also be hollow. Using a hollow structure helps save materials and reduce weight. The cross-sectional shape of both the first horizontal beam 111 and the first vertical rod 112 can be, but is not limited to, rectangular, circular, triangular, etc. This application uses a rectangular shape as an example. The material of both the first horizontal beam 111 and the first vertical rod 112 can be, but is not limited to, metal, plastic, etc. Of course, in other embodiments, the first vertical rod 112 may not be provided on the main gate assembly 110. For example, the first vertical rod 112 can be replaced with a lightbox for advertising, or an LED board can be used instead of an advertisement for promotion.

[0055] The secondary gate assembly 120 is detachably connected to the rear main frame assembly 30. The secondary gate assembly 120 includes two second crossbeams 121 spaced apart vertically and multiple second vertical rods 122. The multiple second vertical rods 122 are spaced apart along the extension direction of the second crossbeams 121 and connected to them. The spacing between the multiple second vertical rods 122 can be the same or different. Both the second crossbeams 121 and the second vertical rods 122 can be hollow, thus saving materials and reducing weight. The cross-sectional shape of the second crossbeams 121 and the second vertical rods 122 can be, but is not limited to, rectangular, circular, triangular, etc.; this application uses a rectangular shape as an example. The material of the second crossbeams 121 and the second vertical rods 122 can be, but is not limited to, metal, plastic, etc.

[0056] The second crossbeam 121 is telescopically inserted into the receiving space Q of the first crossbeam 111 along a predetermined direction F (e.g., Figure 4 (As shown). The preset direction F is the relative direction between the main gate assembly 110 and the secondary gate assembly 120. During the assembly of the main gate assembly 110 and the secondary gate assembly 120, the size of the gate 10 in the preset direction F can be adjusted by changing the insertion depth of the second crossbeam 121 in the first crossbeam 111, thereby adapting to the width of different access channels.

[0057] At least one locking assembly 130 is provided between the two first crossbeams 111 and the two second crossbeams 121. The locking assembly 130 is used to lock the main door assembly 110 and the secondary door assembly 120 together (e.g., ...). Figure 4 (As shown). The locking assembly 130 presses against the first crossbeam 111 and the second crossbeam 121.

[0058] The locking assembly 130 is used to prevent the second crossbeam 121 from moving relative to the first crossbeam 111 along the preset direction F. Specifically, the locking assembly 130 presses the first crossbeam 111 and the second crossbeam 121 in a direction perpendicular to the preset direction F. When the first crossbeam 111 and the second crossbeam 121 are subjected to an external force from the preset direction F, the locking assembly 130 applies a frictional force along the preset direction F to the pressed first crossbeam 111 and the second crossbeam 121. This frictional force will prevent the first crossbeam 111 and the second crossbeam 121 from moving relative to each other in the preset direction F. In other words, this application uses the pressing effect of the locking assembly 130 to lock the first crossbeam 111 and the second crossbeam 121 together.

[0059] In summary, in the door panel 10 provided in this application, since the second crossbeam 121 is telescopically inserted into the first crossbeam 111, the overall width of the door panel 10, composed of the main door panel assembly 110 and the secondary door panel assembly 120, can be adjusted to adapt to different sizes of access passages. Furthermore, since the locking assembly 130 exerts a compression effect on the first crossbeam 111 and the second crossbeam 121, when the first crossbeam 111 or the second crossbeam 121 is subjected to an external force from a preset direction F, the locking assembly 130 will generate a frictional action along the preset direction F on the compressed first crossbeam 111 and the second crossbeam 121. This frictional action can prevent the first crossbeam 111 and the second crossbeam 121 from moving relative to each other in the preset direction F. Therefore, the locking assembly 130 can lock and fix the main door panel assembly 110 and the secondary door panel assembly 120 together.

[0060] The following describes, with reference to the accompanying drawings, two specific structures of the locking assembly 130 and the locking principle of the locking assembly 130 on the first crossbeam 111 and the second crossbeam 121.

[0061] The first type of locking component structure ( Figures 3 to 8 )

[0062] In one feasible implementation, the locking assembly 130 achieves a fixed connection between the first crossbeam 111 and the second crossbeam 121 solely through the diagonal brace 131. Specifically, the locking assembly 130 includes the diagonal brace 131, which is disposed within the receiving space Q and located between the inner wall surface of the first crossbeam 111 and the outer wall surface of the second crossbeam 121. The diagonal brace 131 presses against the inner wall surface of the first crossbeam 111 and the outer wall surface of the second crossbeam 121 to fix the first crossbeam 111 and the second crossbeam 121 together. In other words, the diagonal brace 131 is located between the first crossbeam 111 and the second crossbeam 121. The opposite sides of the diagonal brace 131 respectively press against the first crossbeam 111 and the second crossbeam 121. When the first crossbeam 111 or the second crossbeam 121 is subjected to an external force from a preset direction F, friction will be generated between the first crossbeam 111 and the diagonal brace 131, and friction will also be generated between the second crossbeam 121 and the diagonal brace 131. Through these two frictional actions, the relative movement of the first crossbeam 111 and the second crossbeam 121 in the preset direction F can be prevented, thereby achieving a fixed connection between the first crossbeam 111 and the second crossbeam 121.

[0063] In another feasible embodiment, the locking assembly 130 achieves a fixed connection between the first crossbeam 111 and the second crossbeam 121 through a diagonal brace 131, an outer bushing 132, and a first fastener 133. Specifically, the locking assembly 130 further includes an outer bushing 132 and a first fastener 133. The outer bushing 132 is fixed to the end of the first crossbeam 111, and the outer bushing 132 is provided with a first mounting hole X1. The first fastener 133 passes through the first mounting hole X1 and is connected to the diagonal brace 131. The diagonal brace 131 and the outer bushing 132 work together to compress the first crossbeam 111 and the second crossbeam 121, thereby fixing the first crossbeam 111 and the second crossbeam 121 together. The functions of the diagonal brace 131, the outer bushing 132, and the first fastener 133 are further described below.

[0064] Please refer to Figure 4 , Figures 6 to 8 It should be noted that, Figure 4 and Figure 6The cross-sectional views shown are cut at different positions. The locking assembly 130 includes a diagonal brace 131, an outer bushing 132, and a first fastener 133. The diagonal brace 131 is disposed within the receiving space Q and located between the inner wall surface of the first crossbeam 111 and the outer wall surface of the second crossbeam 121. The outer bushing 132 is fixed to the end of the first crossbeam 111. The outer bushing 132 is provided with a first mounting hole X1, and the first fastener 133 passes through the first mounting hole X1 to connect to the diagonal brace 131, so that the diagonal brace 131 and the outer bushing 132 work together to compress the first crossbeam 111 and the second crossbeam 121.

[0065] Specifically, the first fastener 133 is used to drive the diagonal brace 131 to move along a preset direction F during the assembly process, so that the diagonal brace 131 and the outer bushing 132 abut against each other, and then the diagonal brace 131 and the outer bushing 132 work together to squeeze the first crossbeam 111 and the second crossbeam 121.

[0066] In the first embodiment, the outer bushing 132 deforms under the abutting action of the diagonal brace 131, thereby compressing the inner wall surface of the first crossbeam 111, and the diagonal brace 131 deforms under the abutting action of the outer bushing 132, thereby compressing the outer wall surface of the second crossbeam 121, such as... Figure 7 As shown, in Figure 7 In the middle, the oblique cut of the diagonal brace 131 faces upward, and the oblique cut of the outer bushing 132 faces downward.

[0067] In the second embodiment, the outer bushing 132 deforms under the abutting action of the diagonal brace 131, thereby compressing the outer wall surface of the second crossbeam 121, and the diagonal brace 131 deforms under the abutting action of the outer bushing 132, thereby compressing the inner wall surface of the first crossbeam 111. That is, in Figure 7 Based on the structure shown, the oblique cut of the diagonal brace 131 is set to face downwards, and the oblique cut of the outer bushing 132 is set to face upwards.

[0068] In the third embodiment, the outer bushing 132 is provided with a conical groove in the middle, and the diagonal brace 131 is provided with a conical structure that matches the shape of the conical groove. The conical structure of the diagonal brace 131 is inserted into the conical groove, and the outer bushing 132 deforms under the abutting action of the conical structure and then abuts against the inner wall surface of the first crossbeam 111 and the outer wall surface of the second crossbeam 121.

[0069] In the fourth embodiment, the diagonal brace 131 is provided with a conical groove in the middle, and the outer bushing 132 is provided with a conical structure that matches the shape of the conical groove. The conical structure of the outer bushing 132 is inserted into the conical groove, and the diagonal brace 131 deforms under the abutting action of the conical structure and then abuts against the inner wall surface of the first crossbeam 111 and the outer wall surface of the second crossbeam 121.

[0070] Of the four implementation methods described above, this application will only provide an illustrative example of the first implementation method.

[0071] Please refer to Figure 9 The outer bushing 132 is provided with a groove X4 that mates with the inclined brace 131, and the inclined brace 131 is located in the groove X4. That is to say, the outer bushing 132 is provided with an inclined groove structure (i.e., groove X4, which can also be called a slanted cut), and the shape of the inclined brace 131 matches the shape of the groove X4, that is, the inclined brace 131 is also provided with a slanted cut.

[0072] Please refer to Figure 9 The outer bushing 132 is annular and is fitted onto the second crossbeam 121 and fixed to the end of the first crossbeam 111. Specifically, the outer bushing 132 can be annular, fitted around the outer periphery of the second crossbeam 121 and fixed to the end of the first crossbeam 111, with at least a portion of the outer bushing 132 located between the inner wall surface of the first crossbeam 111 and the outer wall surface of the second crossbeam 121. This arrangement separates the inner wall surface of the first crossbeam 111 from the outer wall surface of the second crossbeam 121, preventing them from scratching each other during insertion of the second crossbeam 121 into the first crossbeam 111. The outer bushing 132 can be made of an elastic material (such as rubber) or a plastic material (such as plastic), which provides a certain buffering effect between the first crossbeam 111 and the second crossbeam 121, while also preventing the first crossbeam 111 and the second crossbeam 121 from being scratched by the outer bushing 132.

[0073] The outer bushing 132 and the first crossbeam 111 can be fixed using threaded components (such as screws, bolts, etc.). For example, the locking assembly 130 further includes a fastening screw 134. The first crossbeam 111 has a first mounting hole U1, and the outer bushing 132 has a second mounting hole U2. The fastening screw 134 passes through the first mounting hole U1 and is inserted into the second mounting hole U2, with the fastening screw 134 threadedly engaging with the second mounting hole U2. Figure 4 As shown. The outer bushing 132 and the first crossbeam 111 can also be fixed by a snap-fit ​​method, for example, the outer bushing 132 is provided with a snap-fit ​​structure 1321, and the first crossbeam 111 is provided with a first mounting hole U1. The snap-fit ​​structure 1321 and the first mounting hole U1 form a snap-fit ​​connection, such as... Figure 7 As shown. Of course, there are other ways to fix the outer bushing 132 to the first crossbeam 111, which will not be described in detail here. It is understandable that fixing the outer bushing 132 to the first crossbeam 111 by fastening screws 134 or by snap-fitting can make the outer bushing 132 less prone to loosening.

[0074] Please refer to Figure 4 and Figure 6The second crossbeam 121 has an insertion end 121D, through which it is inserted into the first crossbeam 111. A first fastener 133 passes through a first mounting hole X1 on the outer bushing 132 and connects with the diagonal brace 131. The first fastener 133 can drive the diagonal brace 131 to move away from the insertion end 121D along a predetermined direction F, thereby forming an abutment with the outer bushing 132. The diagonal brace 131 and the outer bushing 132 then work together to compress the first crossbeam 111 and the second crossbeam 121, thus achieving a locking effect.

[0075] Please refer to Figure 4 and Figure 6 The gate 10 may further include an inner sleeve 140, which is an annular structure and is fitted around the outer periphery of the insertion end 121D of the second crossbeam 121. This arrangement ensures that at least a portion of the inner sleeve 140 is located between the inner wall surface of the first crossbeam 111 and the outer wall surface of the second crossbeam 121. It is understood that the inner sleeve 140 can separate the inner wall surface of the first crossbeam 111 from the outer wall surface of the second crossbeam 121, preventing them from scratching each other during the insertion of the second crossbeam 121 into the first crossbeam 111. The inner sleeve 140 can be made of an elastic material (such as rubber) or a plastic material (such as plastic), thus providing a certain buffering effect between the first crossbeam 111 and the second crossbeam 121, while also preventing the first crossbeam 111 and the second crossbeam 121 from being scratched by the inner sleeve 140. The inner bushing 140 and the second crossbeam 121 can be fixed by threaded parts (such as screws, bolts, etc.) or by snap-fit, etc. For details, please refer to the previous description of the fixing method of the outer bushing 132 and the first crossbeam 111.

[0076] Please refer to Figure 4 The outer bushing 132 has a first inclined surface M1 facing the second crossbeam 121. The diagonal brace 131 has a second inclined surface M2 facing the first crossbeam 111 and a pressing surface M3 facing the second crossbeam 121. The first inclined surface M1 abuts against the second inclined surface M2. The pressing surface M3 presses against the outer wall surface of the second crossbeam 121. Both the first inclined surface M1 and the second inclined surface M2 can be planar and parallel to each other.

[0077] Specifically, the angle between the relative directions of the first inclined surface M1 and the second inclined surface M2 and the aforementioned preset direction F is greater than 0° and less than 90°, that is, the first inclined surface M1 and the second inclined surface M2 are inclined relative to the preset direction F. When the first fastener 133 drives the diagonal brace 131 to move along the preset direction F away from the insertion end 121D of the second crossbeam 121, the first inclined surface M1 adheres to the second inclined surface M2 and applies an abutting force to the second inclined surface M2. Since the first inclined surface M1 and the second inclined surface M2 are inclined, the abutting force of the outer bushing 132 on the diagonal brace 131 can be decomposed into the following two components: 1. The component of the diagonal brace 131 in the direction toward the inner bushing 140; 2. The component of the diagonal brace 131 in the direction toward the second crossbeam 121. Understandably, the component force of the diagonal brace 131 toward the second crossbeam 121 will force the pressing surface M3 of the diagonal brace 131 to press against the outer wall surface of the second crossbeam 121. Similarly, the reaction force exerted by the diagonal brace 131 on the outer bushing 132 will drive the outer bushing 132 to press against the inner wall surface of the first crossbeam 111, thus achieving a locking effect. Furthermore, the further the diagonal brace 131 is from the insertion end 121D of the second crossbeam 121, the greater the pressing effect of the diagonal brace 131 on the second crossbeam 121, and the greater the pressing effect of the outer bushing 132 on the first crossbeam 111, resulting in a stronger locking effect, and vice versa.

[0078] In one implementation, please refer to Figure 6 The diagonal brace 131 is provided with a second mounting hole X2, and the first fastener 133 is inserted into the second mounting hole X2 and threadedly engaged with it. That is, the second mounting hole X2 is a threaded hole with internal threads, and the first fastener 133 has external threads. The first fastener 133 can be screwed into the second mounting hole X2 with internal threads through its external threads. It can be understood that through the threaded engagement, when the first fastener 133 rotates around its own central axis, it can drive the diagonal brace 131 closer to or further away from the insertion end 121D of the second crossbeam 121, thereby adjusting the locking effect. The first fastener 133 can be, but is not limited to, a bolt, stud, etc.

[0079] In another implementation, please refer to Figure 8The diagonal brace 131 is provided with a second mounting hole X2. The locking assembly 130 also includes a first nut T1 (i.e., a nut), which is disposed on the diagonal brace 131, and the nut hole of the first nut T1 communicates with the second mounting hole X2. The first fastener 133 is inserted into the second mounting hole X2 and the nut hole and is threadedly engaged with the nut hole. Specifically, the nut hole has an internal thread, and the first fastener 133 has an external thread. The first fastener 133 can be screwed into the nut hole with the internal thread through the external thread. When the first fastener 133 rotates around its own central axis, the first fastener 133 can drive the diagonal brace 131 closer to or away from the insertion end 121D of the second crossbeam 121 through the first nut T1, thereby adjusting the locking effect. It should be noted that since the first nut T1 itself has a thread, the second mounting hole X2 can be provided with an internal thread or not. The first fastener 133 can be, but is not limited to, a bolt, stud, etc. The first nut T1 can be made of metal. It is understandable that a metal first nut T1 is readily available and relatively hard, making it less prone to stripping. It should be noted that the first nut T1 and the diagonal brace 131 can be integrally formed, or they can be formed separately and then assembled together.

[0080] Optional, please refer to Figure 8 The second mounting hole X2 includes a first sub-hole X21 and a second sub-hole X22. The diagonal brace 131 also has a notch X3 that penetrates through it. The notch X3 is located between and connects the first sub-hole X21 and the second sub-hole X22. The first nut T1 is disposed within the notch X3, such that the nut hole of the first nut T1 connects the first sub-hole X21 and the second sub-hole X22. It is understood that this arrangement facilitates the installation of the first nut T1, and the first nut T1 will be positioned between the first crossbeam 111 and the second crossbeam 121, making it less likely to detach from the diagonal brace 131.

[0081] In any of the above-mentioned related embodiments, the diagonal brace 131 may be made of a wear-resistant non-metallic material. For example, the diagonal brace 131 may be made of rubber material, i.e., the diagonal brace 131 is a rubber component. Alternatively, the diagonal brace 131 may be made of plastic material, i.e., the diagonal brace 131 is a plastic component. It is understood that using rubber or plastic components can prevent electrochemical reactions and can also isolate the aforementioned fasteners from the first crossbeam 111 and the second crossbeam 121, thereby preventing the first crossbeam 111 and the second crossbeam 121 from rusting.

[0082] For the assembly process of the first locking component structure described above, the outer bushing 132 can be first fitted onto the second crossbeam 121, and the diagonal brace 131 can be connected to the outer bushing 132 using the first fastener 133. Then, the second crossbeam 121 can be inserted into the receiving space Q of the first crossbeam 111, and the outer bushing 132 can be inserted into the first crossbeam 111. The outer bushing 132 can be fixed to the first crossbeam 111 using the fastening screw 134. At this time, the usable width of the door panel 10 can be adjusted to match the size of the access passage. Finally, the first fastener 133 can be tightened so that the diagonal brace 131 and the outer bushing 132 abut against each other to work together to squeeze the first crossbeam 111 and the second crossbeam 121, thereby achieving the locking effect.

[0083] The second type of locking component structure ( Figures 10 to 17 )

[0084] Please refer to Figures 10 to 13 The locking assembly 130 includes a locking member 135. A portion of the locking member 135 is sleeved on the outer periphery of the first crossbeam 111 to compress the first crossbeam 111, and another portion of the locking member 135 is sleeved on the outer periphery of the second crossbeam 121 to compress the second crossbeam 121, thereby preventing the second crossbeam 121 from moving relative to the first crossbeam 111 along the preset direction F. In other words, the locking member 135 simultaneously holds the first crossbeam 111 and the second crossbeam 121, thereby locking the first crossbeam 111 and the second crossbeam 121 together. The locking member 135 has a simple structure, good overall consistency, and can provide a better locking effect.

[0085] Please refer to Figure 11 The second crossbeam 121 has an insertion end 121D, through which it is inserted into the first crossbeam 111. Please refer to... Figure 11 The gate 10 may further include an inner sleeve 140, which is fitted around the outer periphery of the insertion end 121D of the second crossbeam 121. For a description of the insertion end 121D and the inner sleeve 140, please refer to [link to relevant documentation]. Figure 4 and Figure 6 The description in the corresponding embodiment.

[0086] Please refer to Figure 12 and Figure 13The locking member 135 includes a first sleeve 1351, which has a first receiving cavity Y1 and a first opening Y2 that are connected to each other. The first receiving cavity Y1 is used to receive the first crossbeam 111, and the first receiving cavity Y1 is adapted to the outer contour shape of the first crossbeam 111, so that the first sleeve 1351 can effectively hold and compress the first crossbeam 111. For example, if the cross-sectional shape of the first crossbeam 111 is rectangular, the first receiving cavity Y1 is a rectangular chamber; if the cross-sectional shape of the first crossbeam 111 is circular, the first receiving cavity Y1 is a circular chamber.

[0087] Furthermore, the locking assembly 130 also includes a second fastener 136, which is connected to the first sleeve 1351. The second fastener 136 is used to adjust the size of the first opening Y2 to change the size of the first receiving cavity Y1. It can be understood that the smaller the first receiving cavity Y1, the tighter the first sleeve 1351 grips the first crossbeam 111, and the stronger the compression effect; conversely, the larger the first receiving cavity Y1, the weaker the compression effect. Therefore, during installation, the locking degree of the first sleeve 1351 can be adjusted according to requirements using the second fastener 136.

[0088] Please refer to Figure 13 and Figure 14 The first set 1351 includes a first extrusion part 1351b, a first connecting part 1351c, a second extrusion part 1351d, a first adjustment part 1351a, and a second adjustment part 1351e.

[0089] The first adjusting part 1351a, the first pressing part 1351b, the first connecting part 1351c, the second pressing part 1351d, and the second adjusting part 1351e are sequentially bent and connected, and together form the first receiving cavity Y1. The first pressing part 1351b and the second pressing part 1351d are disposed opposite each other and are used to jointly press the first crossbeam 111. Both the first adjusting part 1351a and the second adjusting part 1351e face the first connecting part 1351c.

[0090] The first adjustment part 1351a and the second adjustment part 1351e are opposite to each other and spaced apart to form the first opening Y2, and the first adjustment part 1351a and the second adjustment part 1351e are connected to the second fastener 136.

[0091] The second fastener 136 can adjust the distance between the first adjusting part 1351a and the second adjusting part 1351e, thus changing the size of the first opening Y2. If the first opening Y2 becomes smaller, the first adjusting part 1351a will move the first pressing part 1351b closer to the second pressing part 1351d, and simultaneously, the second adjusting part 1351e will move the second pressing part 1351d closer to the first pressing part 1351b. That is, the first pressing part 1351b and the second pressing part 1351d move closer to each other, and the first receiving cavity Y1 decreases accordingly, resulting in a stronger pressing effect. Conversely, if the first opening Y2 becomes larger, the first adjusting part 1351a will move the first pressing part 1351b away from the second pressing part 1351d, and simultaneously, the second adjusting part 1351e will move the second pressing part 1351d away from the first pressing part 1351b. That is, the first pressing part 1351b and the second pressing part 1351d move further away from each other, and the first receiving cavity Y1 increases accordingly, resulting in a weaker pressing effect.

[0092] Furthermore, the first adjusting part 1351a is provided with a first receiving hole V1, which penetrates the first adjusting part 1351a in a direction toward the second adjusting part 1351e. The second adjusting part 1351e is provided with a second receiving hole V2, which penetrates the second adjusting part 1351e in a direction toward the second adjusting part 1351e. The second fastener 136 is simultaneously inserted into both the first receiving hole V1 and the second receiving hole V2.

[0093] In one implementation, please refer to Figure 14 The second fastener 136 is a threaded part with external threads (such as a bolt or stud), and at least one of the first receiving hole V1 and the second receiving hole V2 is a threaded hole with internal threads, and the threaded hole forms a threaded engagement with the second fastener 136, so that the spacing between the first adjusting part 1351a and the second adjusting part 1351e can be adjusted by using the threaded engagement.

[0094] In another implementation, please refer to Figure 15 The second fastener 136 is a threaded component with external threads (such as a bolt or stud). The locking assembly 130 also includes a second nut T2 (i.e., a nut). At least one of the first receiving hole V1 and the second receiving hole V2 is provided with the second nut T2, and the nut hole of the second nut T2 forms a threaded engagement with the second fastener 136. In this way, the threaded engagement can be used to adjust the spacing between the first adjusting part 1351a and the second adjusting part 1351e. The second nut T2 can be made of metal. It is understood that a metal second nut T2 is readily available and has a hard texture that is not prone to stripping. The second nut T2 and the locking component 135 can be integrally formed or separately formed and then assembled together.

[0095] Please refer to Figure 12 and Figure 13 The locking member 135 includes a second sleeve 1352 connected to the first sleeve 1351. The second sleeve 1352 has a communicating second receiving cavity Z1 and a second opening Z2. The second receiving cavity Z1 is used to receive the second crossbeam 121, and the second receiving cavity Z1 is adapted to the outer contour shape of the second crossbeam 121, so that the second sleeve 1352 can effectively hold and compress the second crossbeam 121. For example, if the cross-sectional shape of the second crossbeam 121 is rectangular, the second receiving cavity Z1 is a rectangular chamber; if the cross-sectional shape of the second crossbeam 121 is circular, the second receiving cavity Z1 is a circular chamber.

[0096] Furthermore, the volume of the second receiving cavity Z1 is smaller than that of the first receiving cavity Y1, so as to fit the smaller second crossbeam 121. The second set body 1352 and the first set body 1351 can be an integral structure. The integral structure has greater strength and is conducive to improving the locking effect of the first crossbeam 111 and the second crossbeam 121.

[0097] Furthermore, the locking assembly 130 also includes a third fastener 137, which is connected to the second sleeve 1352. The third fastener 137 is used to adjust the size of the second opening Z2 to change the size of the second receiving cavity Z1. It can be understood that the smaller the second receiving cavity Z1, the tighter the second sleeve 1352 grips the second crossbeam 121, and the stronger the compression effect; conversely, the larger the second receiving cavity Z1, the weaker the compression effect. Therefore, during installation, the locking degree of the second sleeve 1352 can be adjusted according to requirements using the third fastener 137.

[0098] Please refer to Figure 13 and Figure 16 The second set 1352 includes a third extrusion part 1352b, a second connecting part 1352c, a fourth extrusion part 1352d, a third adjusting part 1352a, and a fourth adjusting part 1352e.

[0099] The third adjusting part 1352a, the third pressing part 1352b, the second connecting part 1352c, the fourth pressing part 1352d, and the fourth adjusting part 1352e are sequentially bent and connected, and together form the second receiving cavity Z1. The third pressing part 1352b and the fourth pressing part 1352d are arranged opposite each other and are used to jointly press the second crossbeam 121. The third adjusting part 1352a and the fourth adjusting part 1352e both face the second connecting part 1352c.

[0100] The third adjustment part 1352a and the fourth adjustment part 1352e are opposite to each other and spaced apart to form the second opening Z2, and the third adjustment part 1352a and the fourth adjustment part 1352e are connected to the third fastener 137.

[0101] The third fastener 137 can adjust the distance between the third adjusting part 1352a and the fourth adjusting part 1352e, thus changing the size of the second opening Z2. If the second opening Z2 becomes smaller, the third adjusting part 1352a will move the third pressing part 1352b closer to the fourth pressing part 1352d, and at the same time, the fourth adjusting part 1352e will move the fourth pressing part 1352d closer to the third pressing part 1352b. That is, the third pressing part 1352b and the fourth pressing part 1352d move closer to each other, and the second receiving cavity Z1 will decrease accordingly, resulting in a stronger pressing effect. Correspondingly, if the second opening Z2 becomes larger, the third adjusting part 1352a will cause the third extrusion part 1352b to move away from the fourth extrusion part 1352d. At the same time, the fourth adjusting part 1352e will cause the fourth extrusion part 1352d to move away from the third extrusion part 1352b. That is, the third extrusion part 1352b and the fourth extrusion part 1352d move away from each other, and the second receiving cavity Z1 will increase accordingly, and the extrusion effect will be weaker.

[0102] Furthermore, the third adjusting part 1352a is provided with a third receiving hole W1, which penetrates the third adjusting part 1352a in the direction toward the fourth adjusting part 1352e. The fourth adjusting part 1352e is provided with a fourth receiving hole W1, which penetrates the fourth adjusting part 1352e in the direction toward the fourth adjusting part 1352e. The third fastener 137 is simultaneously inserted into both the third receiving hole W1 and the fourth receiving hole W1.

[0103] In one implementation, please refer to Figure 16 The third fastener 137 is a threaded part with external threads (such as a bolt or stud), and at least one of the third receiving hole W1 and the fourth receiving hole W1 is a threaded hole with internal threads, and the threaded hole forms a threaded engagement with the third fastener 137, so that the spacing between the third adjusting part 1352a and the fourth adjusting part 1352e can be adjusted by using the threaded engagement.

[0104] In another implementation, please refer to Figure 17The third fastener 137 is a threaded component with external threads (such as a bolt or stud). The locking assembly 130 also includes a third nut T3 (i.e., a nut). At least one of the third receiving hole W1 and the fourth receiving hole W1 is provided with a third nut T3, and the nut hole of the third nut T3 forms a threaded engagement with the third fastener 137. In this way, the spacing between the third adjusting part 1352a and the fourth adjusting part 1352e can be adjusted by using the threaded engagement. The third nut T3 can be made of metal. It is understood that a metal third nut T3 is readily available and has a hard texture that is not prone to stripping. The third nut T3 and the locking component 135 can be integrally formed or separately formed and then assembled together.

[0105] In any of the above-mentioned related embodiments, the locking member 135 may be a wear-resistant non-metallic part. For example, the locking member 135 may be made of rubber material, i.e., the locking member 135 is a rubber part. Alternatively, the locking member 135 may be made of plastic material, i.e., the locking member 135 is a plastic part. It is understood that using rubber or plastic parts can avoid electrochemical reactions and can also isolate the aforementioned fasteners from the first crossbeam 111 and the second crossbeam 121, thereby preventing the first crossbeam 111 and the second crossbeam 121 from rusting.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
